>>47826289>most Pokémon with either of those two typings are defensively-oriented.I feel like Rock does a better job of making Pokemon with defensive stat spreads viable offensively. Sure, you have things like Shuckle (which already has a niche) and Corsola (which is straight garbage forever), but most other Rock-types tend to have a way to function in an offensive capacity. Even fucking Coalossal with its 80/80/30 offenses shines the brightest as a potent sweeper in VGC. High access to Speed boosting moves like Rock Polish and even Shell Smash
SS Golem when? tends to help most Rock-types out of pure uselessness, though giving more Rocks access to the Swords Dance + Accelerock combo would be a definite boon to most members of the type. Defensively, high Sturdy rates and the Sand Sp. Def bonus mean that most Rock-types can at least survive for a turn to potentially inflict some damage even if they have to go second.
>>47826343There's a wide gulf between "takes extra damage from bad matchups sometimes" and "literally over half of the Pokedex slaps this monster for triple damage because of STAB and type advantages". Tyranitar is a goddamn rock star for remaining high tier when something like 600 monsters and forms can bop it without even relying on specialized coverage. How many people would complain if total weaknesses were capped at five per Pokemon, with primary type weak points being assigned first? Under this model, Tyranitar loses its Bug and Fairy vulnerabilities since Dark is its second type, but retains a 4x to Fighting since Rock is already weak to that. It would make order of types actually relevant for some 'mons, at least.
